Allelopathic inhibition of phytoplankton by exudates from Stratiotes aloides
The allelopathic potential of exudates from the aquatic macrophyte Stratiotes aloides on the growth of phytoplankton was investigated. A selection of phytoplankton species, occurring in habitats similar to that of Stratiotes, was used: two cyanobacterial strains (toxic and non-toxic Microcystis aeru...

| description | The allelopathic potential of exudates from the aquatic macrophyte
Stratiotes aloides on the growth of phytoplankton was investigated. A selection of phytoplankton species, occurring in habitats similar to that of
Stratiotes, was used: two cyanobacterial strains (toxic and non-toxic
Microcystis aeruginosa), one green alga (
Scenedesmus obliquus) and one eustigmatophyte (
Nannochloropsis limnetica). The results indicate allelopathic effects of
Stratiotes on phytoplankton in six of the eight cases, expressed in an extended duration of the initial biovolume doubling time. The overall inhibitory effect (8–51%) was strain-specific for the two cyanobacteria. We also studied the effect of irradiance on the allelopathic potential of exudates from
Stratiotes. Irradiance influenced the response of
Scenedesmus only. The inhibitory effect of
Stratiotes exudates on the growth of this green alga was stronger at 35
μmol
m
−2
s
−1 than at 105
μmol
m
−2
s
−1. We conclude that
Stratiotes has allelopathic effects on phytoplankton, and that irradiance can, but does not always determine the extent of the allelopathic inhibition. In our experiments, the sensitivity of cyanobacteria to
Stratiotes exudates was not higher than for other phytoplankton strains, but within cyanobacteria, the toxic strain was more sensitive than the non-toxic one. |
